Tired of taking his son to overcrowded public swimming pools, this Chinese father decided to build an inexpensive, private indoor pool for his son. Using steel wires and a sheet of plastic, he turned the back of his microvan into a small pool.

I've seen this done in the back of a pickup truck before, but if you think about it, this is a really good idea. Not only does this guy not have to worry about his kid drinking other peoples' pee or picking up pinkeye at a really crowded public pool, he's figured out a way to keep his tyke away from the sun's damaging rays as he splashes around.
